Lying right to your face (6x6 Rellik sudoku)

(Published on 31. January 2024, 22:48 by sujoyku)

This puzzle is the result of a slightly absurd idea: I have asked myself if it could be interesting to know for a killer cage to which value the contained digits do not sum. Of course, this alone would be quite arbitrary information. But what if not even a subset of the contained digits was allowed to sum to the given value? This brought me to introducing the Rellik Cages (described in more detail below). The clue of such a cage indicates a “forbidden” sum for all contained digits. I like to thank CaptZebraCakes who tested the puzzle and helped me with finding a more concise wording of the rules. As a 6x6 sudoku this puzzle is meant as an introductory example for the new rule set. I do not know yet if it works well in the classic 9x9 setting, but I would definitely like to create a more challenging puzzle of this variant. Please feel free to share your suggestions and opinions in the comments. I wish you happy solving!

- Normal irregular 6x6 Sudoku rules apply, i.e. each row, column and region has to contain the digits from 1 to 6.

- Rellik Cages: All cages are Rellik Cages. Any combination of one or more digits within a Rellik Cage CANNOT sum to the value in the top left.

Example: A Rellik Cage with given value 6 may not contain (1,2,3), (1,5), (2,4) or a 6.

Here you can solve the puzzle online:

Solve on CtC

Solution code: Row 3 from left to right (6 digits in total)

Fantastic new killer-variant! Took me a few minutes to wrap my head around the solving methods involved, after that it was pretty straight forward. Thanks a lot!

After I set a puzzle with a similar constraint, gdc informed me of the existence of this puzzle and this constraint! This was great fun, thank you sujoyku and gdc!

**
Thank you for the comment, SamuPiano! I am glad that you enjoyed the puzzle and thought in the same direction in your own setting. Just to make sure: Are you referring to the puzzle "Pacify"? I have seen, but not yet solved that one.
Kind regards, sujoyku

**
Yes, that's the one! The constraint I used allows repeats, but otherwise it is the same concept.

fun puzzle, if with an unfortunate visual effect... hopefully not on purpose

**
Thank you for your comment, suessersenf! I am glad that you had a fun solve. Concerning the layout issue: As I have replied to other comments below, I try to be more careful about the visual appearance with my upcoming puzzles.
Kind regards, sujoyku

took way too long for me due to missing a very obvious column deduction I somehow didn't spot and had to have a solution video point out for me...100% smooth sailing otherwise, really enjoyed it!

Thank you for your comment, PhoenixAki! I am glad that you enjoyed the solve.

Wow, I absolutely love this idea! Excellent execution for an introductory puzzle as well. Thank you very much!

**
Thank you for the kind words, dumediat! I am glad that you enjoyed this introductory puzzle. If you like to try some harder puzzles of this variant, I have also uploaded an 7x7 and an 8x8 puzzle with the Rellik rule set.

added "6x6 Rellik sudoku" to the title due to a recommendation of CHalb, no changes to the contents of the puzzle

Vorschlag: Ergänze "Rellik Sudoku" im Titel. Ich hatte Schwierigkeiten, dieses Rätsel zu finden, trotz des "Lying" im Titel.

**
Vielen Dank für den Hinweis, CHalb! Ich habe den Titel nun abgeändert. Da es das erste Rätsel mit der Rellik-Regel war, hatte ich es ursprünglich nicht in den Titel gesetzt, weil sich darunter niemand etwas hätte vorstellen können. Nochmals vielen Dank für deine Aufmerksamkeit!
Viele Grüße, sujoyku

I had to try the first Rellik puzzle after testing a WIP using this variant ;). Wonderful idea, I am impressed by the number of variant of variant that are still created. Thank you for setting and sharing :).

**
Thank you for your kind comment, goodcity! I am glad that you liked the variant.
Can you tell me what WIP stands for?
Kind regards, sujoyku
**
WIP stands for Work In Progress, so a puzzle in testing with this variant but not released yet !

**
Ah, thank you for the clarification. I know what work in progress means, but did not recognize the abbreviation. Is the mentioned puzzle by Flinty?
**
It might be ;)

**
I only asked to know if you like some assistance. If so, I would gladly test some of his (your? ^^) ideas. I wish you good luck setting!

I very much enjoyed this. It was great iterating back and forth as the cages forced their number-bond counterpart into the other cage/part of the region.

**
Thank you for your comment, AdiBoneHead! I am glad that you enjoyed the logic of the puzzle.
Kind regards, sujoyku

Took a minute to wrap (or unwrap) my head around the new rule, but once I did, it was a treat. Thanks for setting!

You are very much welcome, Ryx, thank you for your comment! I am glad that you enjoyed the solve.

Fun constraint! I might now start thinking of standard cages as wrogn relliks.

**
Thank you for your comment, sacklunch! I am glad that you had a fun solve. Thinking of regular killer cages as twisted Relliks is a very cute way to put it. :)
Kind regards, sujoyku

If I hadn't read The Bard's comment, I never would've noticed that Rellik was Killer backwards - haha. I might need to borrow this constraint if you don't mind. Very nice puzzle, I love nip and tuck, back and forth logic like this.

**
Thank you for your kind comment, Flinty! Feel free to use this constraint for your own puzzle. I would love to see what you do with it. I am still kind of experimenting with the rule set myself.
Kind regards, sujoyku

Very nice puzzle. I like the constraint, the name and the execution.

Oh, I think I might have noticed what you are referring to ...
I will have to be more cautious where to place cages/regions in my next puzzles.

Thank you for your appreciative comments @Snapper, @lordovol and @Puzzle Weasel! I am glad that you enjoyed the puzzle. Can anyone let me in on the "seeing things"-joke? Have I unintentionally made some reference with the "Lying right to your face" title?
Kind regards, sujoyku

Great idea, excellent introductory puzzle. I look forward to more!

on 1. February 2024, 17:01 by lordovol
Nice puzzle but I'm seeing things too :(

on 1. February 2024, 11:27 by Snapper
Interesting Idea.
Thanks for the puzzle!

on 1. February 2024, 08:52 by sujoyku
Thank you all for your kind and encouraging comments! I will continue to work on my understanding of which Rellik clues allow for interesting interactions and try to build a harder puzzle. Of course, everybody is invited to jump on and build their own Rellik puzzle.
Kind regards, sujoyku

i would very much like to see this in a 9x9.

Wow, that was super fun! Really cool idea

Cool idea to have "anti-killer" (Rellik) cages. I would love to see more of this idea.

**
Thank you for your comment, The Bard! I am glad that you liked the idea of anti-killer cages. The name was chosen in analogy to Nabner lines. I think the relation Renban/Nabner is similar to that one between Killer and Rellik cages.
Kind regards, sujoyku
